Global Payments is the only Merchant we work with where you can apply a refund in IO and have it automatically get refunded back to the customer through the Merchant. With the other Merchants we partner with, you must record a negative payment in IO, but you'll need to manually process the refund through that companies software. For example, if you are using Square, you must manually refund the customer from Square. Once you have refunded the customer from Square's software, you must go into IO and manually record the refund.
Many of our Merchants offer the feature of recharging cards. However, recharging and refunding are two different features.
Recharging - Recharging saved credit cards that have been previously stored on file for the customer (returning customer, paying the balance, scheduled payments, etc)
Refunding - Refunding the customer the amount agreed upon (full balance, deposit, etc)
This is how to process a refund through IO for Global Payments:
Make sure you are under the "Charge Existing Card" section on payments. Next you will enter the negative dollar amount that you are refunding back to the customer in the amounts box, then click "Charge Card".
This is how to record a refund once you refund the customers card in your merchants software. This is what you would do if you are not using Global Payments:
To record a refund, enter the refund amount in the Amount field, prefixed with a negative sign. You may also select the payment type — for example, choose Cash if the refund was issued in cash. Please note that this process only records the refund in the system; it does not physically process the payment. The recorded refund will be reflected in the Total Balance Paid, so adjust the amount as necessary to ensure accurate records.
